    Physics: Post your doubts here!

    You are quoting this from the physics as level course book. I don't understand why the question is saying the sum of the masses is not equal when if you compare both sides, the masses seem to be equal to me.

    But if you compare the masses on both sides, they seem to be equal. They're both 236 on both sides

    But the mass is 236 on both sides. I'm so confused.

    For this particular question, do we need the current that passes through the ammeter or the current that passes through the wire AC? They would be different. These two currents would be less than the current that passes through CB. I think.

    Physics: Post your doubts here!

    Which current though?
  14. Asad Moosvi

    Physics: Post your doubts here!

    In order to calculate the pd across AC, do we have to look at the current that passes through the ammeter or the wire AC itself? (I am confused.)
